Key Properties
Thioacetamide (extra pure) is a widely used sulfide source, historically important as a hydrogen sulfide-generating reagent in qualitative inorganic analysis. It is a colorless to white crystalline solid that is soluble in water, making it suitable for various laboratory applications. With a molecular weight of 75.13 g/mol and a purity of 98.5%, this compound is essential in the synthesis of thiol compounds and as a reagent in organic chemistry. Its role as a controlled-release hydrogen sulfide source is particularly valuable in metal-sulfide precipitation testing, where it aids in the identification of metal ions through the formation of insoluble sulfides.
Also known as Thioacetamide, Thioacetamide, 2-Thioacetamide.
